Example 2

During the drilling operation, the broken rock debris is washed by the flushing fluid when the guide hole is drilled, and the rock debris is lifted out of the drill hole by the flushing fluid along the annular space between the drill rod and the hole wall. The friction between the well-flushing fluid and the drill rod easily causes unsmooth slag discharge, and the drill rod is easily disturbed, the accuracy of drilling is influenced,

in order to solve the above problem, the present embodiment provides a drilling machine further including a friction reducing drill rod, and referring to fig. 4, the friction reducing drill rod includes: the well-flushing device comprises a rod body 110, wherein a well-flushing fluid flow path 111 arranged along the axial direction of the rod body 110 is arranged inside the rod body 110, and a drag reduction structure is arranged on the outer surface of the rod body 110.

When the device works, the well washing liquid is output from the lower end of the rod body 110 through the well washing liquid flow path 111, rock debris is driven to be lifted out of a drill hole through an annular space between the rod body 110 and the hole wall, and a resistance reducing structure is arranged on the outer surface of the rod body 110, so that the friction force between the well washing liquid and the surface of the rod body 110 is reduced, unsmooth slag discharge is avoided, the disturbance of the well washing liquid to a friction reducing drill rod is reduced, and the accuracy of the drill hole is improved.

Referring to fig. 5, the drag reduction structure is a plurality of grooves 121 provided on the surface of the rod body 110. Specifically, a plurality of rotating discs 120 are arranged on the rod body 110, the surface of each rotating disc 120 coincides with the surface of the rod body 110, and each rotating disc 120 is provided with a groove 121.

When the well-flushing fluid flows through the groove 121, turbulent flow is generated at the groove 121, and the friction force between the well-flushing fluid and the rod body 110 is reduced according to the turbulent flow resistance reduction effect.

Different operational environment, it is different to fall friction drilling rod rotational speed, and the relative flow direction that falls friction drilling rod of well-flushing liquid is also different for same friction drilling rod from the top down different positions department, adjusts the angle of recess 121 as required through rotating carousel 120 to make the main aspects of recess 121 unanimous with the rivers direction to most advanced direction, furthest reduces frictional force, and the guarantee is arranged sediment smoothly.

More specifically, a controller and a driving mechanism for driving the turntable 120 to rotate are also included. The driving mechanism is controlled by the controller to drive the turntable 120 to rotate, so that the angle of the turntable 120 can be adjusted at any time during work.

More specifically, the density of the grooves 121 is gradually increased from top to bottom along the surface of the rod body 110. The pressure increases with the depth of the flushing fluid, so that the friction is higher the rod body 110 is subjected to the flushing fluid from top to bottom, and the friction is reduced to a greater extent by increasing the density of the grooves 121.

Referring to fig. 6, the groove 121 is shaped like a drop whose direction from the large end to the tip coincides with the water flow direction. From the big end to the small end of the groove 121, the width and the depth are reduced, and the water flow forms turbulent flow at the groove 121 through the big end; the depth is gradually reduced by gradually transiting to the small end, so that the resistance to water flow is reduced.

Referring to fig. 7, an interlayer 122 is disposed at the bottom of the groove 121, a sealed space is disposed inside the interlayer 122, the sealed space is filled with gas, and an elastic material is disposed on a side of the interlayer 122 close to the groove 121.

When the pressure outside the interlayer 122 is lower than the pressure inside the interlayer 122, the sealed space inside the interlayer 122 increases, the bottom of the groove 121 elastically deforms toward the outside of the interlayer 122, and the space inside the groove 121 decreases;

when the pressure outside the interlayer 122 is greater than the pressure inside the interlayer 122, the sealed space inside the interlayer 122 decreases, the bottom of the groove 121 elastically deforms toward the inside of the interlayer 122, and the space inside the groove 121 increases.

The flow rate and the depth of the grooves 121 influence the turbulence. The rotating speeds of the friction-reducing drill rod in different working environments are different, so that the speeds of the well-flushing liquid relative to the surface of the friction-reducing drill rod are different. When the flow velocity of the water flow is too fast, an excessive turbulent flow is generated at the groove 121, thereby increasing the resistance of the water flow and causing unsmooth slag discharge. In this embodiment, the interlayer 122 is disposed at the bottom of the groove 121, and when the flow rate of the water is too fast, the pressure outside the interlayer 122 is smaller than the pressure inside the interlayer 122, so that the bottom of the groove 121 is elastically deformed, the depth of the groove 121 is reduced, the size of the turbulent flow is reduced, and the resistance is reduced.

In other embodiments, the turntable 120 is coupled to the shaft 110 via a bearing and is capable of freely rotating. Since the depth of the large end is greater than that of the small end in the groove 121, the resistance to the flow of liquid from the large end to the small end is smaller than that from the small end to the large end. Therefore, by providing the rotating disc 120 capable of rotating freely, the resistance of the water flow to the groove 121 can automatically adjust the angle of the groove 121.

Example 3

Referring to fig. 8, on the basis of embodiment 2, the friction reducing drill rod of this embodiment further includes a stabilizing ring 130, the stabilizing ring 130 is sleeved on the rod body 110, and the outer diameter of the stabilizing ring 130 is larger than the outer diameter of the rod body 110.

When the well-flushing fluid flows through the stabilizing ring 130 from bottom to top, a liquid gasket is formed by the circumferential turbulence of the stabilizing ring 130, when the friction-reducing drill rod is deviated, the compressed turbulence of one side of the liquid gasket is close to the hole wall, the liquid pressure is increased, and therefore the friction-reducing drill rod is aligned.

Specifically, the lower surface of the stabilizer ring 130 is in inner arc transition with the connection portion of the rod body 110. The resistance of stabilizing ring 130 to the flushing fluid is reduced by the radiused transition.

More specifically, the stabilizer ring 130 is provided in plural number and is axially fitted over the rod body 110. A plurality of stabilizing rings 130 are arranged from the top to the bottom according to the length of the rod body 110.

Example 4

In this embodiment provides, friction-reducing drill rod, on the basis of embodiment 2, still includes the rivers flow direction sensor that sets up at the body of rod surface, and rivers flow direction sensor sends rivers flow direction signal to the controller, and the controller passes through drive arrangement and adjusts the corner of carousel 120, makes the big end of recess 121 unanimous with the rivers direction to the direction at most advanced. The flow direction of the water flow is sensed by the water flow direction sensor, so that the angle of the turntable 120 can be automatically adjusted by the controller, and different working conditions can be automatically adapted.

More specifically, the rod body 110 is divided into a plurality of sections from top to bottom, each section is provided with a water flow direction sensor, and the controller independently controls the direction of the rotating disk 120 of the corresponding section according to the water flow direction sensor. When the well washing device works, the friction reducing drill rod rotates to drive the well washing liquid to rotate, and the flowing speeds of the well washing liquid rotating from top to bottom are different, so that the flowing directions of the well washing liquid relative to the friction reducing drill rod are different. The water flow direction sensors are arranged in different areas, and the angles of the rotary discs 120 in the opposite areas are independently controlled, so that the angle of the groove 121 is ensured to be the same as the flow direction of the relative friction reduction drill rod of the well flushing fluid to the maximum extent.
